UNIVERSAL VISE AND WORK-HOLDER To all whom it may concern:

- I Be it known that we, LAWRENCE Snow and EMIL- F. MiiLLER PETERSEN, respect vely a citizen of the United States and a Sllhjqt of the King of Denmark, residing at R11, cine, in the county of Racine and State of Wisconsin, have invented certain new and useful Im rovements 1n Universal'Vises and -Work-Ho ders, of which the following is a specification. r

invention relates to a universal vise and workholder adapted for use on milling machines, drill presses, grinders, or the like.

'Withthe above and other objects in view,

V as will appear as the nature of the invention v the novel construction and combination of is better understood, the same consistsin artsof a universal vise, work holder and the like, as will be hereinafter fully dey scribed and claimed; 4

the standard to a milling machine, drill press, grinder, bench or to any objeetde sired.

The standard 1 is tapered and is designed to engage a similarly shaped socket in a ball 4, the upper end of the standard being proilded with a threaded socket 5 to receive the threaded terminal of a screw 6, the head portion of the block being rounded to constitute a continuation of the periphery of the ball, as shown in Fig. 6. To prevent the ball from havnig any rotary motion upon .the standard, the latter and: the ball are each provided with'a tapered groove, and these two grooves register and present a seat to receive a key or pm 10 that is driven upward through the basc-plate Mounted. upon the ball and-conforming to its'curvaturejs a block or cap 1.1 fitted with a clamping ring 12 and a clamping or retain ing band 13, therefor, said band being Suit ably provided with notches or sockets l l'rto be engaged by a pin wrench by which the band may be turned. To, hold-the band 13 assembled with theblock'or cap 11, the latter is provided ekteriorly witlra semi-circular race I5 and the band interiorly'with a 00111-- plemental race 16, and these two races are plied through an opening in the. band that -is normally closed by a) threaded plug 18,,

That'portio'n of the socket that is engaged by the band is circumferentially reduced to providea downwardly facingshoulder 19', and this will receive the thrustof the band and relieve the balls of undue friction,

As will be noted by reference to-Fig. 2,

moved upward and the cap downward and The, grooves 8 ofthe hall are -enga'gedby engaged by bearing balls'17 that aresupthe lower edge of the clamping-ring is'dis: posed below the'eenter ofthe .ball' l so thatwhen the band is turned the ring willbe 00 thus firmly clam' Ithela't'ter againstinovement and at any esired angular adj'iistment.,

two bolts '20 mounted ,in'alinediorifices the-cap,- and each of these'bolts is provided withitwo seats-21 that-- are designed tof be' engaged by :a 3 vertically arren'ged 'sfbring To permit "insertion elidfremoval 01-13110 6' pressed pin 22, which, by'coaction with the bolts'27 from the... ohve'28, the inner will! seats, Wlll serve to hold the bolts either in fof'the'groove fiscutawdjiht one point/.1
